1. Introduction. Let µ be a continuous (i.e., without atoms) positive Radon measure on the complex plane. The truncated Cauchy integral of a compactly supported function f in L p (µ), 1 ≤ p ≤ +∞, is defined by Ꮿ ε f (z) = |ξ −z|>ε f (ξ) ξ − z dµ(ξ), z ∈ C, ε > 0. In this paper, we consider the problem of describing in geometric terms those measures µ for which |Ꮿ ε f | 2 dµ ≤ C |f | 2 dµ, (1) f...

Wireless transmission of compressed visual information presents new challenges in image coding and reconstruction techniques. Unlike the traditional error-free media for which current coding standards have been designed, wireless channels do not offer guaranteed transmission, and data loss over such channels can result in catastrophic errors in the decoded visual information. Visual data, howev...

1.1 Introduction Mathematical morphology is a discipline of image analysis that was introduced in the mid-1960s by two researchers at thé Ecole des Mines in Paris: Georges Matheron [1] and Jean Serra [2, 3]. Historically, it was the first consistent non-linear image analysis theory, which from the very start included not only theoretical results but also many practical aspects. Due to the algeb...

BACKGROUND Increased prevalence of visual impairments has been reported in preterm populations. However, it remains unclear about the long-term visual electrophysiological outcomes and their association with visual cognitive functions in premature infants. We investigated visual electrophysiological outcome of 2-year-old infants of different birth weights by flash visual evoked potentials (FVEP...

A novel visual capability, the detection of circularly polarised light, has been demonstrated in a mantis shrimp, a colourful crustacean from tropical reefs.

Till Stina och Moa i ABSTRACT Product development implies a need for information processing capability due to its uncertain and ambiguous nature. Uncertainty is troublesome as it limits an organization's ability to plan for, and make decisions about, the activities that need to be made in order to reach the objectives of the organization. Ambiguity stems from individuals having differing interp...
